My top margin is missing

If you're reading in Print Layout view and the top and bottom margins appear to have been cut off, that means the option for hiding the white space between pages of the document is switched on. You can restore the margins by pointing and clicking in the document, or by using the View tab.

Point and click to see or hide the margins

Point to the top or bottom of a page until the pointer becomes a double-pointed arrow, and then double-click.
